The Builder's Story
I built CityHenge with zero prior coding experience, using Claude Code and AI-assisted development. What started as a personal curiosity became 188,000 lines of code across seven programming languages.
The app runs on a self-hosted Ubuntu server with Docker containerisation, security hardening, and automated backups. The companion Helios database catalogs 78+ community datasets across Greater Sydney.
For photographers, explorers, and anyone chasing beautiful moments. There's always another alignment coming.
